Nut, even circumferential offers opening on the outer circumference surface of the screw rod, and the opening is connected to the mounting hole, the opening
Screw rod is divided into the rising bar of several circumference uniform distributions, the mounting hole internal screw thread is equipped with threaded post, and the one of the threaded post
End is fixedly installed with tightening piece, and the tightening piece is in truncated cone-shaped, when the tightening piece is mobile to head from the end of screw rod, gradually
Several rising bars are strutted.
The anti-drop bolt of the utility model coaxially opens up mounting hole, even circumferential on the outer circumference surface of screw rod on screw rod
Opening is offered, opening is connected to mounting hole, and screw rod is divided into the rising bar of several circumference uniform distributions, mounting hole internal screw thread by opening
Threaded post is installed, when the utility model is used, bolt is plugged in mounting hole, screw thread installs nut on bolt, so
Upward rotary threaded column afterwards, one end of threaded post are fixedly installed with tightening piece, and tightening piece is in truncated cone-shaped, what threaded post rotated upwards
Meanwhile driving tightening piece mobile from the end of bolt to head, rising bar is strutted during tightening piece is mobile, makes rising bar
Always it being contacted with the inner wall of nut, on screw rod, nut is not easy to loosen nut tensioner, more it will not fall off, nut and bolt
Fixation is stronger, and the mechanical erection using the utility model bolt is more stable.
Threaded rod is adjusted for the ease of rotation, the head opens up the adjustment hole with mounting hole coaxial communication, the screw thread
The other end of column is fixedly installed with adjusting block, and the adjusting block is located in the adjustment hole, and the adjusting block cross-sectional shape is
Hexagon is easy to use outer hexagonal spanner that adjusting block is adjusted.
Threaded rod is adjusted for the ease of rotation, offers adjusting blind hole, the adjusting blind hole on the end face of the adjusting block
Cross-sectional shape be hexagon, be easy to use allen wrench adjusting block is adjusted.
Further, the screw rod includes fixing end and thread segment, and the fixing end is connect with head, and the opening is located at
On thread segment, the nut thread is mounted on thread segment.
The beneficial effects of the utility model are: the anti-drop bolt of the utility model, mounting hole is coaxially opened up on screw rod,
Even circumferential offers opening on the outer circumference surface of screw rod, and opening is connected to mounting hole, and screw rod is divided into several circumference by opening
Uniformly distributed rising bar, mounting hole internal screw thread are equipped with threaded post, when the utility model is used, bolt are plugged in mounting hole
Interior, screw thread installs nut on bolt, and rotary threaded column, one end of threaded post are fixedly installed with tightening piece, tensioner then up
Block is in truncated cone-shaped, while threaded post rotates upwards, drives tightening piece mobile from the end of bolt to head, tightening piece movement
Rising bar is strutted in the process, contacts rising bar with the inner wall of nut always, for nut tensioner on screw rod, nut is not easy pine
It is dynamic, it more will not fall off, the fixation of nut and bolt is stronger, and the mechanical erection using the utility model bolt is more stable.
